Overfishing can be sustainable. [dubious – discuss] According to Hilborn, overfishing can be "a misallocation of societies' resources", but it does not necessarily threaten conservation or sustainability". [2] Overfishing is traditionally defined as harvesting so many fish that the yield is less than it would be if fishing were reduced. [2]
Illegal and unreported fishing contributes to the reduction in fish stocks and hinders the ability for fish populations to recover. It is believed that between 10 billion and 23 billion instances of illegal and unreported fishing happen annually, with communities in developing countries being more likely to partake in these illegal activities.

In 1999, China set an objective of “zero growth” in coastal marine capture catch, and in 2001 changed the objective to “minus growth ". To achieve this, China has been reducing vessel numbers and relocating fishermen away from marine capture fisheries.
The problem of overfishing are as follows: the catches of wild fish have peaked and are now in decline, rational fishery management is the exception rather than the rule, the most valuable fish is trawled to the point of extinction, the developed world is stealing from both the developing world and the future generations, and fish farming, the ...
The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs.
The United States is competing to stay ahead of China on AI and its use in weapon systems. The focus on AI has generated public concern that future wars will be fought by machines that select and ...
China's 2005 reported harvest was 32.4 million tonnes, more than 10 times that of the second-ranked nation, India, which reported 2.8 million tonnes. [2] China's 2005 reported catch of wild fish, caught in rivers, lakes, and the sea, was 17.1 million tonnes. This means that aquaculture accounts for nearly two-thirds of China's reported total ...
